ADVANCED: Swappable spells 🪄 (Arcana)

[thorny hamlet]

Hiiyaa! This question is for a datapack I'm working on called Arcana (not my main project It Spreads), where I want to use the new item components to create wands with spell slots you can swap out and switch between. I have a few ideas for how to do this, but I'm interested to see what other people can come up with. Basically, I want to store spells in the custom data of a Wand item, and use the consumable component to give the spells custom cooldowns, casting times, and animations. The biggest problems currently are getting the item back after consuming it, updating the spell when it is swapped, adding and removing spells from the wand, and displaying the selected spell (which changes while shift-clicking). It also needs to work in mainhand and offhand.

I'm not really sure where to start here, is the issue that you don't know how to do any of this? Cause it sounds like you know exactly what to do

That's certainly what I would do, so I don't think you're gonna get a whole lot of alternative methods. Only thing I might do differently is not have the wand actually get consumed so you don't need to worry about giving it back

[thorny hamlet]

I know how to use most things that I'll need in order to accomplish this, I'm just really not sure how to do these things specifically

[thorny hamlet]

Wait, how would I do that?

[tender galleon]

The normal consumable-right-click-detection method

[thorny hamlet]

I'm using the consumable component as-intended, since the process has to finish in order to make everything else work

[tender galleon]

Unfortunately it requires you use a scoreboard timer as the method of cooldown, but imo that's a small tradeoff for a much easier system

[tender galleon]

Which things? It seemed like you listed every thing

[thorny hamlet]

I'm not really sure how to get the item back easily

[tender galleon]

Then I think you're gonna end up with more complications, primarily with as you identified, giving back the same item that was consumed

Yeah, I'm frankly not super sure either. The fact it's such a dynamic item makes that tough

[thorny hamlet]

Is it possible to make the consume_remainder be the original item?

[tender galleon]

You'd probably need to store the item's data to storage before consumption, but that runs into trickiness when a player has more than one wand

[tender galleon]

I don't think so, again because it is so dynamic

[thorny hamlet]

Hmmm

Is it possible to, like, update it whenever it would change?

[tender galleon]

You can make it give back a wand with pre-loaded spells, and make an option for every combination of spells, detecting which ones the old wand had to determine which to give

But obviously that would suck

[tender galleon]

I don't quite understand the question

[tender galleon]

Oh wait I guess you might be able to store the current item into its own use_remainder component?

That sounds really janky, I'm not actually certain it's possible or would work

[thorny hamlet]

Hmmmmmm

Would I be able to save it to storage, and detect a specific use_remainder item in mainhand/offhand and replace it with the stored item somehow??

[tender galleon]

Presumably

I'm not super experienced with using data storage, but that sounds feasible. Certainly detecting the dummy use remainder item is, as is replacing it with something

So it just comes down to how easy it is to have that replacement incorporate data from storage

[thorny hamlet]

Could I possibly copy it to an armor stand and run a data store command thingy to store the item into itself and then give it back?

[tender galleon]

Sure

[thorny hamlet]

It would be hella janky lol

[tender galleon]

The armor stand would certainly be jankier by definition

But also easier

[thorny hamlet]

I think neither way is straightforward at all 😭😭

Like, I'm planning to use advancements to detect the usage

[tender galleon]

Welcome to data packs 😅

[tender galleon]

For sure

[thorny hamlet]

lmaoo

[thorny hamlet]

hmmm

I've decided I'm gonna have a spellcast function when the wand is used that will copy it over

Basically, I'll just detect when the wand is eaten and give it to an armor stand/item display/item and stuff it back into itself

...

we use the weirdest freaking coding language ever don't we 😭

I use a different system than you and this is still 1.19(?) (I forgot) but you can maybe get some ideas out of it.

[thorny hamlet]

Oooooo!

Ty! I'll check this out

[thorny hamlet]

Thanks! That's fairly straightforward, tyy

I think I'll try to do something similar, but make modified versions for swapping vs using

[thorny hamlet]

So ummmm

How should I switch like

The selected slot

actually I have an idea for that nvm

Anyways, I'm wondering how to swap out the spells

Anyone have any ideas? :3

[vocal chasm]

you want to modify the spell data?

what about /data

[tender galleon]

Probably an item modifier

[sharp cargo]

I would use an item modifer.

[thorny hamlet]

How would one use an item modifier for that?

[tender galleon]

What do you know about item modifiers currently?

[thorny hamlet]

Well, I was planning to use them to change the consumable component and the lore and stuff for each spell

[tender galleon]

So what then isn't clear about how you'd use it to change the custom data component?

[thorny hamlet]

I'm... not really sure how to switch the spells in the different spell slots on it

[tender galleon]

You can't, really. You have to overwrite the entire custom data component. So, you'd need some way to both determine which slot is being replaced, and retain what the other slot is

There is the option of using custom enchantments that don't have any behavior of their own to represent the spells, and I could see a few routes to go there

[thorny hamlet]

I was also thinking in, like, a less technical manner

Actually umm

[tender galleon]

Elaborate 🤔

[thorny hamlet]

Like

Like how should I make the player able to change out the spells? Some kind of custom crafting table? A GUI? Is it possible to basically take each custom data spell slot and turn it into some kind of spellbook or scroll that stores the spell, and then be able to rearrange or add new ones and turn them back into data?

[thorny hamlet]

Anyways, I will try to implement some of these things ^^

[tender galleon]

Really more of a creative question

[thorny hamlet]

I suppose!!

[thorny hamlet]

Alright, I'll try to figure this out and then come back if I need help :3
